CAN-SOLDERING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 696,550, dated April l, 1902.

Appnanmnea .Tammy is, 1901. serai No. 43,794. iN@ modem To @ZZ whom, z'ft may concern:

Be it known that we, JAMES I). COX and FRANK A. ODIN,'of Bridgeton, in'the county of Cumberland, and in the State of New Jer- 5 sey, have invented certain new and useful Improvements in Can-Soldering Machines; and we do hereby declare that the following is a full, clear, and exact description thereof,

reference being had to the accompanying der-feeding mechanism. Figs. 9 and l() are respectively detail views of the devices for 2o moving the solder-guiding tubes to and from the soldering-tools and for controlling the feed of the solder. Fig. 11 is a detail View in perspective of the saidfeeding devices; and Fig. 12 is a detail view, in end elevation, of the acid-applying mechanism. f

Letters of like name and kind refer to like parts in each of the iigures. I

The object of this invention is to provide a power-machine for soldering caps on cans 3o whose various movements will be lautomatic, which will have capacity for a large amount of work, and yet be comparativelysimple and i inexpensive; and to these ends said invention consists in the machine andin the parts thereof combined substantially as hereinafter specified.

Brieiiy stated, the .machine comprises la movable table or support for the cans to be capped, mechanism for supplying suitable 4.o acid or linx to the cans, soldering-tools, and means for supplying solder to the latter. The frame of the machine is composed of two similar sides A and A, .that are suitably connected together by rods or bars B and B, one of which is at .the top. '.lhesoldering-tools C and C are arranged in two parallel gangs or rows, each being mounted on the lower end of a rod or spindle D, on which is fastened a pinion d, that in common With the pinion d 5o of the opposite soldering-tool of the other row Ameshes with and receives motion `from a pin- Figs. 7. and 8 are respectively detail views of the sol.

ion E, that is connected with the hub of a bevel-pinion F. The latter and the pinion E are journaled on a vertical shaft G, which is fastened to a horizontal plate Il, that forms part of a frame in which the soldering-tools are mounted. The bevel-pinion F is in mesh with and is driven from a like pinion I upon a horizontal shaftK, thatis journaled in bearings in the frame sides Aand A, one end of said shaft having mounted on it a sprocketwheel L, that is connected by a chain M with a sprocket-wheel N on the driving-shaft O, journaled in bearings in the frame sides A and A, near the bottom of the latter.

The frame supporting the soldering-tools Cand C has two side pieces P and P, that are pivoted at their, upper ends to the shaft K, while to their lower endsY is attached the furnace, consisting of a horizontal plate Q, with a depending flange q, which surrounds the y gangs of tools C and C and gas-burners R and R. The latter are arranged so that one is centered between and heats four solderingtools, each burner being attached to a valved branch pipe s, that is connected to a main pipe S, which has communication with a suitable supply Of gas. A valve T in the main pipe S enables the iiow of gas to all of the burners to be controlled at once, while any required regulation of the burners separately can be effected by the valves in the branches s and s.

The frame carrying the soldering-tools is pivoted to the shaft K in order that the tools maybe swung into such position as to give access to them for cleaning, retinning, or replacement. Chains U and U, connected, respectively, at one end to the frame sides l and F and at the other end to a shaft V, upon which they may be wound by means of a crank if, enable the frame andtools to be swung as described. The shaft `V is provided with a ratchet-wheel e for engagement by a dog NV to enable the frame and tools to be secured in the position to which they may be swung. By disengaging the dog the frame will swing to place the tools in normal operating position. For locking the frame in the latter position there is provided a spring-bar X, which is fastened at one end to one ol' the side frames A and has atits free end a pin fr,

IOC)

which passes through an opening in said frame and enters a hole in the side of one of the pieces P. On the spring-bar X is a knob a3', by which the bar may be moved to free the pin from the plate Q.

It will be apparent that by the construction described access to the soldering-tools can be had without putting out the fires orstopping the machine.

To enable the soldering-tools to be adjusted vertically, the bearings of the shaft K are formed each in a vertically-movable block Y, which is secured to the outer side of a frame side A by bolts Z and Z, passing through vertical slots y and y in the block. The vertical position of theblock is fixed by means of an adjusting-screw A', that is tapped through a lug gj', projecting horizontally from the block Y, and has its head abutting against a lug a, projectinghorizontally from the frame side A.

The solder for the tools C and C is in the form of wire wound on reels or spools B' and B' on a plate, which connects the two frame sides A and A, there being a reel or spool for each tool. From the reel the wire passes to guiding and feeding mechanism, by whichit is carried in just the proper quantity to the soldering-tool. The feeding mechanism consists of two oppositely-arranged rollers C' and D', the former having a toothed or roughened periphery and being mounted on a shaft E', journaled in bearings on the frame sides A and A, and the other having a smooth periphery with inclined sides and journaled in bearings on a pivoted bar F', by the adjustment of which the pressure or grip of the two rollers on the wire may be regulated. A short rod G', pivoted at one end to a bar H', that is fixed relative to the bar F', and passing through an open-ended slot in the top of the bar F', and a thumb-nut l' on said rod G', between which andthe side of the bar F' is a coiled spring K', constitute suitable means for such adjustment of the grip or pressure. Before passing betweenthe rollers the wire goes through a guiding-eye fon the bar F', and from said rollers the wire passes into and through a guide-tube L', whose lower end is turned horizontally to direct the wire against the side of the soldering-tool C. The upper end of the tube L' is secured to an eye at the lower end of the bar H', and as the latter is pivotallymounted on the shaft E' the guide-tube is capable of having its lower end movedtoward and fromA the solderingtool. Thus as soon as the requisite quantity of solder has been fed to the tool the tube is moved away from near the tool to a point where it cannot be affected by the heat et' the tool and the solder within it melted, causing waste thereof and an insufficient supply to succeeding cans, so that the latter are defectively sealed. The means for producing this movement of the guide-tubes consist of a bellcrank lever M', pivoted to one of the frame sides A, one arm of which is connected by a link N to a bar O', which is connected with the series of guide-tubes, and the other arm of which is connected to a lever P', that is pivoted to one of the frame sides A, being moved in one direction in the manner to bc hereinafter described and in the opposite direction by a spring Q'.

For the twofold purpose of further protecting the solder from the heat of the irons and to prevent the chilling or cooling of the irons there is placed on each side of the furnace a shield R', of some material that is a non-conductor of heat, which is movably supported that it may be interposed between the irons and solder when the latter are retracted and taken out of the way when the solder is to be moved into contact with the-irons. VSome movements of the shields are preferably automatically produced, each shield being suspended from the ends by a pair of chains S' and S', that after passing over pulleys Tand T' are fastened to the respective bars O' and O'. When the latter are moved toward the irons,l they will draw on the chains, and thus lift the shields out of the path of the solder, while when said bars are moved in the opposite direction the shields will descend by gravity. The shields shown consist each of a sheet or layer of asbestos between sheet metal plates. Certain ot' the pulleys T' and T' are mounted on the shafts E' and E', others, in the case of those for one shield, areplaced on the shaft V, and the remainder, in the case of those for the other shield, are supported on armsf' andf'. Upon the similar ends of the shafts E' and E' are respectively two gears e and e, each of which meshes with one of two intermeshed gears U' and U', journaled on stub-shafts on the side of a frame A. On one of said stub-shafts and connected with one of the gears U' is a sprocket-wheel V', over which passes a sprocket-chain W', that also passes around an idler-wheel X', journaled on a stub-shaft lower down on said frame A. Pivoted to a bracket Y' on the adjacent frame A is a horizontal lever Z', having at one end a pair of jaws, one of which, a, is fixed and the other of which, e', is pivoted, by which the chain may be gripped and through the movement thereof" moved. For moving the movable jaw to cause the chain to be gripped and then moving the lever to impart movement to the chain a vertically-movable bar A2 is employed, whose upper end has the form of'a hook a2, adapted on the descent of the bar to engage a lateral lug z2 on lthe movable jaw a'. When freed from the hook, the jaw releases the chain by gravity, and the lever is returned to position for repeating the operation by a coiled spring B2, that is attached at one end to the lever 4and at the other end to the frame A. For limiting the ascent of the jaws by the action of the spring a stop is provided, which to permitof adjustability yis in the form of a vertical screw y2 in a lug on the bracket Y', against which a lateral lug on the lever strikes. By mov- IOO ITO

ing the screw up or down the swing of the lcver may bc varied, and consequently greater or less movement of the chain secured and more or less solder fed to the irons. Should it be considered unnecessary to provide for variation in the quantity of solder fed, the barhook a2 could engage directly with the chain, and thus the jaw-carrying lever be omitted. Vertical movement of the bar A2 is secured by pivoting its lower end to a crank C2 on a shaft D2, connected by gears E2 and F2 to the driving-shaft O. Near its upper end the bar is slidably connected by a strap or loop g to one arm of a lever G2, pivoted to the frame. Another arm of said lever is connected by an adjustable link H2 with the lever P', While a third arm thereof is connected to a spring Q2. By the movement of the lever P, acting through the lever G2, the bar A2, which is continuously reciprocated by the crank C2, `is moved to engage its hook'ct2 withthe jaw-lug .32, while by the action ofthe springQthrough said lever G2 the bar is disengaged from the lug. Thus an intermittent movement is imparted to the sprocket-chain and from it through the gearing described to the solderfeeding devices.

The acid or flux is containedin a pan or trough T2, that extends across the machine between the two frame sides A and A, being supported from the latter by brackets a2 and a2.

YSupported above it are two shafts K2 and K2,

on each of which are mounted a series of dippers 7.: and t, which take from the pan the required quantity of acid for each soldering operation and deliver it to the cans. On the shafts are meshing gear-segments k andA 7s', respectively, one of which by a link or rod k2 is connected to a rod or shaft L2, mounted to move vertically through guides or brackets crandct4 on one of the frames A. By the ascent of the rod the shafts are` rocked to tilt the dipper 7c andt' to lift the acidfout of the pan and deliver it to the cans,and by its descent said ngers are returnedto the pan. The rod is suitably weighted, as by an enlargement Z on its upper end, to cause it to move to its lowest position. tally and to move vertically in bearings on the same frame A as that on which the rod L2 is mounted is a shaft M2, which at its upper end has an arm m, that by the rocking of the shaft may be moved to or from aposition beneath the lower end of the rod-L2. `Said shaft is normally held with the arm m from beneath the the rod L2 by means of a coiled spring N2, attached to one end of the arm m or an extension thereof and to the frame A` at its other end, and saidshaft is moved to place the arm m beneath the rod by means of a curved arm O2 on the shaft, that projects in the path of the cans as thelatter are moved along toplace them below the acid-supplying mechanism. By lifting the shaft M2 when thc arm misbeneaththe rod L2 thelatter will be raised and the di pper carrying shafts Mounted to turn horizon' rocked to deliver acid to the cans. y For 1nov ing said shaft M2 vertically there is jpivotally connected to its lower end one end of a lever P2, whose other end is engaged by a cam Q2 on the shaft D2.

A tank or reservoir R2, supported on a bracket 0n the side of .the frame sides A and connected by a pipe r with the pan T2, supplies acid to the latter, while a second tank S2, also supported on a bracket on said frame side, is provided to receive any overflow from the pan, a pipe s2 being run from the latter to the tank S2. l

The cans to be operated on are supported in two parallel rows on a tray T2, which is placed upon a horizontal bed U2, that rests upon two pairs'of levers V2 and V2 at its respective ends, said levers being pivoted to the frame sides A and A and the levers of a pair being extended in opposite directions and engaging each a rounded lug or boss 'zt on the under side of the bed U2. Pivoted on the same pivot with each lever V2 is a rod or bar V2, the under side of which isI engaged by a screw "U2, tapped through the lever V2, and which is connected by a `link X2 with a lever Y2, that engages a cam Z2 upon the shaft D2. By the revolution of said cam the bed is caused to have a rising-and-falling movement, the reason for which will hereinafter appear. By means of the bar W2 and the screw ft2 the level of the bed can be adjusted. To confine the bed in position as it rises and falls, a bar A2 is pivoted at one end to each side thereof, which at its other endlis pivoted to the frame side A. Secured to the bed in position to enable it to engage a stud or projection j) on the lever l is an: arm fa, whichon the descent of the bed will engage said stud should the spring Q failto act, and thus positively move the lever. Tolpermit adjustment in view of the adjustability of the bed, the arm it is made in two parts united by a slot-.and-bolt connection.

Upon the bed are two rails B2andl32, upon which the tray rests and along-whichit may slide, and there are two guide-bars C2 and C2 upon the bed 4to engage the respective ends of the tray and hold it from endwise movement in either direction. For `moving the tray there are two longitudinally movable bars D2 and D2, which are placed in slots'in the bed, being each grooved in one side to engage the side wall of its respective slot, and

having pivoted dogs d and d. to engage the edge of the tray. Said dogs are of a familiar construction which permits the tray todepress and pass over them in `one direction, but resists movement in the opposite direction. A bell-crank lever E2, connected at one end to the two bars D2 and D2 andengaged at its other end by a cam F2 on the shaft D2, constitutes means whereby the revolution of the cam causes the reciprocation of the bars.

`On the drive-shaft O there is provided suitable clutch mechanism G2, by which the IOO IIO

` shaft M2.

sprocket-wheel N may be clutched to and unclutched from the shaft to control the revolution of the soldering-tools.

The operation of the machine is as follows: A tray containing two rows of cans is placed on the rails B3 and B3 with its edge in position to be engaged by the outermost dogs d and d. The bars D3 and D3, being moved by the cam F3, pass the cans to a position beneath the acid-feeding mechanism, and at the same time the cam Z moves the bed with the tray of cans thereon upward, so that they are close to the dippers. In the inward movement of the tray the cans at those ends of the rows next the arm O2 engage and move the latter, and thus turn the shaft M2 to place the arm m beneath the rod L2, which is lifted, as hereinbefore described, by the cam Q2, acting to raise the The acid being delivered to the cans, the bed is permitted to drop, and the bars I)3 and D3, by the revolution of the cam F3, having in the meanwhile been retracted and again advanced, bringing the second set of dogs d and d against the tray, the forward travel of the latter is continued and the cans brought to position beneath the soldering-tools, and the elevation of the bed being repeated the can-tops are moved up to place them in contact with the soldering-tools, and at the same time by the engagement of the tray with the lever P the solder guiding and feeding devices are operated to lift the shields R and R, swing the tubes L and L to place the ends of the solder against the tools, and to feed the predetermined amount. The solder-tools having performed their work, the bed descends, permitting the lever P to be moved by the spring Q' to remove the solderguiding tube away from the tools, stop the feed of the solder, and lower the shields. The tray is next removed from the machine.

It will be seen that the operation of both the acid-feeding and solder-feeding mechanisms depends upon the presence of the cans or trays in the machine, and hence if the machine is run without them there will be no 'operation of said mechanisms, andso no loss of either acid or solder.

While the machine shown has two rows or sets of soldering-tools, it is to be understood that one row or set can be used and the number of tools varied and that other changes can be made in respect to details of construction which will involve no departure from our invention. IVe also wish it understood that though we prefer to control the feed of acid or flux by means of the cans we regard the use of the tray instead as within the scope of our invention, and we also consider the substitution of the cans for the tray as the means for controlling the feed of the solder as within the scope of our invention.
